How to comply for this code
Methodology guide -- electricity (CN 2716)
Electricity is the only CBAM commodity where the customs declarant is typically not the actual generator's customer -- it is a TSO or trader. The methodology mirrors that.
Step 1: identify the country of origin. For CN 2716 the "origin" is the third country whose grid is the source. The CBAM Implementing Regulation publishes annual CO2 emission factors for non-EU grids.
Step 2: choose between country-default and verified data. Verified data requires plant-level metering, contractual chain of custody and verifier sign-off -- only a handful of large industrial off-takers will manage this.
Step 3: account for grid losses. The factor in Annex IV is at the border, not at the source plant -- losses are already included.
Step 4: monitor coupling status. If the third country joins the EU electricity market (full day-ahead coupling), CBAM may be waived. Switzerland is the live test case.
